Hi
Can anyone help me as to where I can obtain a longer rear Campagnolo hub axle? My old freewheel cassette had a recess on the lockring face, but on the new freewheel there’s no recess, which shortens the axle length (129mm).

Many thanks
PP

Assuming you need a hollow axle, here's a good deal if this listed item is 10mm x 26tpi. Maybe send a note to the seller to ensure it's not 9.5mm.

edit: I don't shop Amazon much, but here's a decent deal as well:

I've heard on a recent thread here that it really doesn't matter much to the cones whether the axle has 26 TPI (Campagnolo [and Sturmey-Archer]) or 25.4 (1.0 mm, everyone else) thread pitch. YMMV.

Jeff Wills

Oh, it matters. They're not interchangeable at all.

Wheels Mfg. has axles in both threads and many lengths. I used one of their QR rear axles, 10mm x 26tpi x 146mm, to put a C-Record hub in a 135mm spacing frame.

Maybe There's something I'm missing here, isn't the axle length determined by the rear dropout spacing? On all the campy hubs I've dealt with the axle didn't come in contact with a freewheel. A freehub is an entirely different story.

Ham fisted hammer mechanic advice !!!

If it doesn't fit get a bigger hammer!


This illustration shows the Thread Pitch Error between 26 Threads Per Inch and 1mm Pitch. At 4 turns onto the axle there is .02mm difference (.0008"). At 8 turns the error becomes .04mm (.0016") and the cone begins to bind. 12 turns results in a .06mm error (.0024") and at 16 turns it's .08mm (.0032")

That doesn't sound like much but a hardened cone will deform the fine pitch threads on the softer steel axle as the cone is forced further on. This can result in cones frequently loosening in use or a cone that's very difficult to adjust or remove.
Wheels Mfg axles don't have slots milled in for keyed lock washers like original Campy axles. Over time, Campagnolo stopped slotting their axles and using those washers because the keys in the washers damaged the axle threads as they were tightened or loosened.




Some other points.

Back in the 70's we had a lot of problems with strong, heavy or curb jumper riders bending or breaking Campy rear axles. Our simple solution was to replace the Campy axles with a complete Zeus 10mm x 1mm axle and cones. They were the same dimensions except for the thread pitch plus the Zeus axles were much stronger and we never had any that broke or bent.

The complete Zeus axles with cones and hardware was less than half the price of just a Campy axle!

The only problem was Campy purists who didn't want their bike contaminated with superior quality Zeus parts!

The other solution was the Wheels Mfg axles made of much stronger heat treated alloy steel. They never bent or broke either!

I have Campy 5 speed rear axles in 129mm, 130mm, 131mm 132mm and 134mm lengths!

The shortest Wheels Mfg Campy style 10mm x 26tpi axle is 141mm. Buy one of those and cut it to length.

I like 4mm to 5mm of axle protruding out of the lock nuts on both sides.

Many thanks everyone for all your
excellent advice…. That’s helped immensely👍👏🏻👏🏻

I think his new freewheel is wider than the original, and his old axle isn't long enough in the dropout. So he needs a new, longer axle. Dropout spacing can usually be widened a tad for whatever hub spacing you're using. Most folks like a little more than 3mm of axle on each side in the dropout.

I've bought a number of WM axles for Campy hubs. On the tabbed (keyed) washers: I grind those tabs off with a Dremel & reuse them. The washers then, go right on w/o issue...

I am looking for a Campagnolo axle cones. Do you know of a source for good ones? I need a sets for front and rear

I was looking at grabbing this for the rear

GIPIEMME COMPLETE REAR AXLE WITH CONES ASSE E CONI NOS, never assembled

· All components are no marked but I think GIPIEMME brand

· Compatible thread with Campagnolo cones

· Hollow axle

· Length of axle mm 130

· Weight grams 90 circa


and for front - still looking. Since they take 7/32nd bearings are there any other companies besides Zeus that are compatible (or was Zeus only god for rears)**********

+1 on the Wheels MFG replacement axles. I think the last one I purchased on Amazon.

SurferRosa

You might ask @Mad Honk.

Mad Honk 

SurferRosa,
The following sources for the cones: Casanova9898 item number 373266392161 and vievelo item number 393204058054 These are pairs of NOS cones. The other option is for Wes to send me his old ones and let me try to repair them. There are other ways such as buying the entire axle and cone sets from cycleguyjack and having spare parts lying around. Or even look for hubs and then have even more spare parts lying around Like I do.

And a note to WES, Zeus was probably God of Rears, and people who acted like horses' rears. Smiles, MH

I may have take you up on the cones.
I traded a 9 speed clincher wheelset for a set tubulars with Campy rims with someone I knew that assured me were "ready to go" - just needed grease. Turns out, not so lucky.

I need a narrow wheelset for a red Schwinn frameset I have that sits forlornly in my garage.... My nephew can't return to Canada with those tubulars I bought off of @Mattdiano as he let his passport expire so he has to stay in New York or he can't go back. I'm resigned to having to build my own wheelset.

Mad Honk 

Wes,
I am sure your phone will reach across the border since I just talked to northern Ontario last night. Call me at 812-336-dave. Yes it is a vanity number, but my golf business needed something the customers could remember; and that pays for my bike indulgences. Smiles, MH

It was only in April, but I was able to purchase a Wheel Manufacturing axle, 10x26x137 (model A-07) from Boulderbicycle.bike but they are OOS now. They still have a 141mm version (model A-08) available for $29.00.

The sell an assortment of vintage Campy hub parts at reasonable prices.

Paging verktyg please.

Resurrecting this old thread with a follow-up question: When Zeusing up a Campy hub, would there be indicator markings on any of the relevant parts? I have a Record hub with an axle that is 141.45mm long, 9.85mm in diameter and does not have the milled slot. The locknut is knurlled on the sides as well as the end that would make contact with the dropout (photo below). While at the co-op yesterday, I found a couple of 129mm axles, marked 'Brev. Campagnolo' on the smooth center section of the axle, also 9.85mm in diameter, though with a milled slot. Not knowing anything about potential tpi issues, I was hoping to use one of these to convert the hub for a new 120mm spaced 5-speed project, but upon removing the existing locknut from the existing axle I find it threads on only a couple of turns (about the length of the locknut itself), which leads me to wonder whether this hub has been Zeused. I removed the rest of the spacers and find no obvious markings (Campy or otherwise) on the existing axle.

1 Lugnut or gkamieneski , did your Wheels Mfg axles have any markings?

I am assuming at this point that I either need new cones and locknuts to use the 129mm axle with this hub, to use another hub, or to just cut down the existing one, but thanks in advance for any insights!

CliffordK

If it is original Campagnolo Nuovo Record, then the cones, and perhaps the lock nuts will be marked.

I'd try your finicky parts on axles you know have 1mm thread pitch.

TPL

10 x 1 ...., and 10 x 26 = ( Campy thread) are NOT interchangeable

Miche hubs use 10 x 26 axles .... Wheels Mfg makes replacement axles in 10 x 26 = ( commopnly available )

TPL

Peletonpete ....from above, freewheels are not cassettes

cassettes are not freewheels

2 entirely different parts that simply will not interchange

100 dollars is yours when you are able to actually install a cassette on a hub made for a freewheel

bicycle parts actually have very specific names

pedals are not 'foot platforms' ....also, no doohickeys, thingamabobs or whatchamacallits

repechage

this reads to me that it is a freehub assembly.
a different axle is going to be a trick.
there were lots of minor but significant changes

This is a mighty old thread that was bumped.

For some reason I believe my old bike was always 126mm making things easier.

As I progressively moved from 2x5 to 2x6 to 2x7 gearing, I simply moved the washers and spacers around between the left and right side of the hub, and seemed to survive. I wasn't too good at dishing years ago, but a bit better now.

Anyway, no need for a new axle when all I needed to do was flip a spacer from one side to the other.

The last freewheel I ended up was a DNP Epoch 7 speed which was just a touch wider than other 7 speed freewheels, but I managed to squeeze a last touch of adjustment out of the axle. I think the company may have started machining for the back side overhang on at least some of their freewheels since that time.

Also, as mentioned above, if one changes the OLD by say 1mm, recenter the axle, and it may well be fine.

Yes, apologies for reawakening this thread, particularly to poor Pete who has been raked over the coals on terminology. I thought it might be good to use this thread as I thought my question was a specific enough follow-up to verktyg's original explanation, which I had found useful in understanding where I had likely gone wrong.

mr_palomar

hello, the campy track axle i have (part no. RH-PI001) appears to be too short for my 120mm r.d.s. frame (i am working on a single speed conversion using a nuovo record hub). i switched out the stock hollow axle for this track axle, which measures 155mm overall. if i could ask, has anyone encountered this? should i head over the wheels manufacturing for their solid axle which is 174mm? many thanks! (and, apologies for adding a new post here but i found this thread, esp. post no. 6 by verktyg, to be super helpful). 🙏
